A think tank is suing the NYPD over its failure to reveal details about its secret facial recognition program. Georgetown University’s Center on Privacy and Technology (CPT) alleges that the department hasn’t complied with New York state’s Freedom of Information Law (FOIL) by forking over information on the system, which the department started using to investigate crimes in 2011. When groups submitted FOIL requests for training manuals and documentation, the NYPD insisted they didn’t have any, so CPT is taking the department to court.
